ALFRED PETTERSON HALD, OF MINNEAPOLIS, MINNESOTA.

GREASE-SCALE.

Application filed May 14, 1915.

l '0 all whom it may concern:

Be it known that I, ALFRED PETTERSON HALD, a citizen of the UnitedStates, and a resident of Minneapolis, in the county of Hennepin andState of Minnesota, have invented a new and Improved Grease-Scale, ofwhich the following is a full, clear, and exact description.

My invention relates to mechanism for holding and distributing greaseand oils of various kinds, my more particular purpose being to provide acontainer for holding the grease or oil and for determining exactly theamount of said grease or oil as removed from time to time.

Stated more in detail, my invention comprehends one or more tanks and aframe for supporting and handling the same, together with a scalecarried by the frame for weighing the tank or tanks from time to time inorder to determinethe amounts of oil or grease removed therefrom.

My invention further comprehends means for shifting the weight of thetank or tanks from the scale to a supporting device located below thescale and carried by the framework.

My invention also comprehends means for steadying the tank or tanks inorder to facilitate the removal of the frame and various parts carriedthereby.

My invention contemplates other improvements upon mechanism of thisgeneral character.

Reference is made to the accompanying drawings forming a part of thisspecification and in which like letters indicate like parts.

Figure 1 is a side elevation of a device embodying my invention andshown as partly broken away and using in this instance only a singletank. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is afragmentary elevation showing the lower part of the frame and partscarried thereby. Fig. 4 is a horizontal section showing my device asused with a plurality of tanks forming ia cluster.

A U' frame 5 is mounted upon caster wheels 6, 7 and provided withbearings 5 in which are journaled crank bars 8, 9, the latter beingprovided with horizontally disposed portions 10 which are straight andflat, and adapted to form a supporting surface. The crank bars 8, 8 arefurther provided with jaws 11 of arcuate form so ar- Specification ofLetters Patent.

ranged as to move toward each other and from each other as the crankbars 8, 9 are rocked.

Mounted rigidly upon the crank bar 8 is a hand lever 12 and pivotallyconnected with this lever is a pitman 13. This pitman is pi votallyconnected to an arm 14, the latter being mounted rigidly upon the crankbar 9. The operator by grasping the hand lever 12 can move it intodifferent positions, as indicated by full and dotted lines in Fig. 3.\Vhen the hand lever 12 is in its extreme position to the left, asindicated in Fig. 3, the crank bars 8, are slightly off center; that is,the supporting portions 10 are slightly nearer together than are theaxial centers upon which the crank bars are adapted to rock.

Mounted upon the U-frame is a T 15 and extending upwardly from this T isa standard 16, the upper portion of which is bent substantially intohorizontal position as may be understood from Fig. 1. Secured to thestandard 16 and extending downwardly therefrom to the frame 5 are twobraces 17, which are curved as indicated in Fig. 2. A tank is shown at18 and carries a quantity of liquid grease 18. Connected with the bottomof the tank is a discharge pipe 19 which is provided with a screen 20,as indicated in Fig. 1. The purpose of the screen is to facilitate theretention and subsequent removal of the impurities including particlesof iron or grit.- The tank 18 is provided at its top with an air-tightfiller cap 18. A hose 21 is con nected with the discharge pipe 19 andcarries a discharge nozzle 22 and a hand valve 23. The purpose of thehose, the discharge nozzle and the hand valve is to enable the operatorto discharge grease from the tank 18 directly into any part of anautomobile or the like as may be desired.

Mounted upon the upper end of the tank 18 is a support 24 having ahorn-like form, and upon this support the hose 21, when not in activeuse, may be rested or coiled. The support 24: is provided with an eye 25and a hook 26 is adapted to extend through this eye. A scale 27, havingin this instance the general form of a steelyard is provided with abearing 28 upon which it is mounted, this bearing having an upwardlyextending bolt 29 which projects through the upper portion of thestandard 16. A wing nut 30 engages the bolt 29 and rests upon theadjacent portion of the standard 16. The scale 27 is provided withappropriate weights 3], 32, and

is otherwise adapted for the purpose of weighing. A pressure gage 33 ismounted upon the tank 18 and serves to indicate the degree of airpressure therein.

Mounted upon the upper end of the tank 18 is a head 3i, provided with avalve 3?) and with a nipple 36. The head is further provided withanother nipple 36 and by the aid of these nipples is used for admitting'air under pressure into the tank 18, and for releasing said airtherefrom as desired. The nipple 36 is an air inlet and is provided witha check valve 36".

The filler cap 18 is used for admitting grease or oil into the tank.

The mechanism shown in Figs. 1, 2 and 3 is used as follows: The tank 18being filled or partially filled with liquid grease, is lifted up andrested upon the portions 10, 10 of the crank bars 8, 9, the hook 26being extended through the eye 25. The hose and various other partsbeing now in position, the operator by moving the handle lever 12 to theright according to Fig. 3 dislodges the supporting portions 10 of thecrank bars from their engagement with the bottom of the tank. The tankis thus left suspended, and the scale 27 can now be used for determiningand indir eating the weight of the grease total within the tank. Thisbeing done, suppose next that the operator wishes to use a portion ofthe grease for filling some receptacle of an automobile or for greasingsome part of the mechanism thereof by the aid of the hose 21, nozzle 22and hand valve 23, the operator draws off from the tank 18 an amount ofgrease suflicient to accomplish the purpose desired. By aid of the scale2-7 he now determines the total weight of the tank 18 and its contents,and this total weight being subtracted from the total weight firstfound, gives the exact amount of grease which has been removed from thetank. After each weighing by aid of the scale 27 it may be desirablethat the tank lS shall no longer hang from the scale, but shall besupported from below. This object is easily accomplished by simplyshifting the hand lever 12, as above described.

The U-form 5 and caster wheels 6, 7, together with the parts carriedthereby, constitute practically a truck from which the tank -18 can bereadily wheeled from one place to another. As a general rule when thisis being done, it is desirable that the tank shall rest upon thesupporting portions 10 of the crank bars as above explained.

In Figi 4, I show a slightly different form of my device. A frame 37 ismounted upon caster wheels 88, 39 and extending upwardly from the frame37 is a standard 40 corresponding to the standard 16 above described. Aboard 41 supports a number of tanks 42, 43, 441, in this instance threein number, arranged as a cluster. By aid of nipples 45, 47,

and a valve 416 air can be introduced under pressure into the tanks. AY-tube 1-8 communicates directly with the tank -12, and by aid of pipes49, 50 also communicates with the tanks 43, 11 in such manner that theair pressure is always alike for all three of the tanks.

Connected with the several tanks 1-2, 1-3, ll. are hoses 51, 53 fordischarging grease therefrom. Mounted rigidly upon the board ll andextending up\ ardly from the same is a suspension rod 5% which at itsupper end carries an eye This eye corresponds to the eye 25 shown inFig. 1, and isadapted to engage the hook 26 carried by the scale.

In using the form of my device indicated in Fig. 4, the cluster of tanks12, 43, 4 1 is treated as a unit for purposes of weighing and forpurposes of establishing and maintaining the air pressure common to thethree tanks. Different kinds of greases or oils, however, are placedwithin the three tanks and are discharged independently through thedifferent hoses 51, 52, The cluster of tanks as a unit is weighed beforeand after each discharge of grease from any one of the tanks. In thismanner the same scale is used to indicate different amounts of greaseremoved from time to time from the different tanks. It may be remarkedin this relation that the removal of grease from a tank to an automobileis ordinarily a more difficult and unsatisfactory undertaking than isgenerally realized. If a grease gun be employed there is the attendantdisadvantage that particles of grit and even small metallic objects suchas bicycle balls are carried in with the grease and liable to do damage.Again, a grease gun has to be carried by hand and must either be verylarge and heavy, or else must be frequently replenished. All of theseattendant disadvantages are done away with by the use of my improveddevice. Moreover, by aid of the invention the operator can determineexactly the amount of grease for which he should charge the automobileoperator, and the device saves considerable time in figuring orestimating the grease thus used.

I do not limit myself to the precise con- 5 struction shown asvariations may be made therefrom without departing from the spirit of myinvention.
